Problem with AJAXcontrolToolkit

I recently updated the toolkit to v7.0607 (if that is the newest one I do not know) And ever since then I have been finding random errors on my site related to controls from the kit. I'm afraid to uninstall it I don't know if I can downgrade?

I have fixed all but two - I haven't found anyone with the same issues. Please help!

1) Drag and Drop functionality for the toolkit is not functioning? All other controls drag and drop fine but when I pull something from the toolkit nothing happens in code behind or on the main page? (Started after the update)

 2) This control isn't working it is doing the opposite - it is suppose to validate Maximum Value of 9999.99 and Minimum of 0.00 - and for the last 3 months (since I put it together) it has worked fine but now it flags any number less than 1000? Says number is invalid?

<asp:TextBox ID="ItemPriceSingleTextBox" Width="60" runat="server" Text='<%# Bind("ItemPriceSingle") %>' ValidationGroup='<%#String.Format("{0}" + "{1}", "validate", Container.DisplayIndex)%>' /><asp:MaskedEditExtender
                        TargetControlID="ItemPriceSingleTextBox"
                        ID="MaskedEditExtender1"
